Can the AMD Radeon RX 7900 XTX run ViT-G (model soup)?

Yes โ€” here's how fast and up to what context, with real measured numbers.

ViT-G (model soup) on the AMD Radeon RX 7900 XTX

QuantFits?Max contextSpeedBeyond context
FP16 yes 258k 164.1-200.5 t/s ~6.8-8.4 (slow)
Q8 yes 286k 328.2-401.1 t/s ~13.7-16.7 (slow)
Q4 yes 298k 586-716.2 t/s ~24.4-29.8 (slow)

Estimate (memory-bound). Beyond "max context" the KV cache spills to system RAM offload (depends on your system RAM) and speed drops to the "beyond" figure.

FAQ

Can the AMD Radeon RX 7900 XTX run ViT-G (model soup)?โ–ถ

Yes. At Q4 it generates ~586-716.2 tok/s and fits up to 298k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~24.4-29.8 tok/s.

How much context fits?โ–ถ

At Q4, up to about 298k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
